This invention relates to a fountain dispenser for fruit juices, milk and other liquids.

.It is an object of the present invention to provide a fountain dispenser for fruit juices, milk and other liquids, which when removed from the container of the liquid being dispensed can be easily and quickly disassembled for the purpose of being cleaned and made sanitary without the need of having additionaltools to eifect this result so that the person at the fountain will find it easy to clean the dispenser.

It is another object of the present invention to provide a fountain dispenser for fruit juices, milk and other liquids having a top structure which can be easily assembled to and disassembled from the top cover of the container for the purpose of being cleaned wherein the spout is removable with the structure with one simple operation upon the structure including the ability of the operating lever to be detached from the cover.

Other objects of the present invention are to provide a fountain dispenser unit which is removable from the container having the liquid to be dispensed, which is of simple construction and wherein the operating pump parts are separable from the unit without the need of tools, and which is inexpensive to manufacture and efiicient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings in which Fig. 1 is a side elevational view of the dispenser unit with portions broken away to show construction of certain of the parts and showing the handle member in both its raised and. lowered positions.

Fig. 2 is a rear elevational view of the unit with the pump chamber broken away to show the interior of the same.

Fig. 3 is a side elevational view of the discon-. necting pin.

Fig. 4 is a side elevational view of the dispenser unit with the pump piston detached from the same and slid outwardly of the pump chamber.

Fig. 5 is a perspective View of the pump piston with the valve plate supported thereon.

Fig. 6 is a fragmentary and sectional view taken through the pump chamber and looking upon the interior thereof.

Fig. 7 is a side elevational view of a modified form of top structure utilizing the features of the present invention with portions broken away to show the interior construction.

Fig. 8 is an elevational view taken at a different angle from the view in Fig. '7 and likewise having portions broken away.

Referring now to the figures, It represents a 4 Claims. (Cl. 222-385) cover having a flange ll adapted to be supported in an opening in a container 12 having the liquid to be dispensed. The cover [0 serves as a base for the unit and depending from the same is a rod 13 to the lower end of which there is connected a pump chamber 14. The rod i3 is secured to the plate by a top nut l5. Also depending from the cover plate and serving to support the chamber 14 at the side thereof opposite from the rod I3 is a conduit or pipe I 6 which is secured to the top of the chamber 14 as indicated at I7. The cover plate Iii has a fitting I8 secured to it in communication with the conduit l6 and on which there can be fitted an outlet spout [9 from which the liquid is dispensed.

On the top of the plate I0 is a projection 2| to which there is pivotally connected a link 22 extending upwardly and providing for a fulcrum connection 23 for an operating lever 24 having a large handle 25.

Laterally spaced from the projection 2| and disposed between the cover and the lever is a telescopic sleeve device 26 for effecting the return of the lever 24 to a raised position. The device 26 is connected to the lever 24 by a screw 21. The inner member is fixed to the cover l0 and extends upwardly from the sleeve to move downwardly thereover. This inner member is indicated at 28. The device 26 includes a spring, not shown.

The chamber I4 is open on the bottom and there extends into the same a piston 3i having openings 32 therein and on which is a valve plate 34. A rod 35 is connected to the piston 3| at the center thereof and extends upwardly through a boss opening 36 and through a boss portion 31 on the plate Id. The upper end of the rod 35 is fiattened as indicated at 39 and has a hole 4| therein. This flattened end 39 is adapted to receive a link 42 having a slot 43 into which the flattened portion 39 of the rod extends. The link 42 is formed of a solid metal cylinder and has at opposite sides of the slot 43, respectively, portions 45 and 46. The portion 45 is threaded as indicated at 4'! to receive a threaded connecting pin 49, Fig. 3, having a threaded shank 5|. Accordingly, the link 42 can be easily disconnected from the rod 35 by simply removing the connecting screw 49. The screw 49 has a large knurled handle portion 52 by which the same can be turned. The rod 35 can thus be quickly and easily released from the parts above the cover plate so that the piston and the rod can be dropped out of the bottom of the chamber [4 in the manner illustrated. in Fig. 4..

, The piston can thus be easily cleaned and access can be readily had to the chamber I4. With the parts easily separable in this manner, the operator of the fountain will not hesitate to clean the interior faces of the chamber and the piston parts. There will thus be no cause for the unit to become unsanitary.

The link 42 is connected to lever 24 by a pivot screw 54. When the disconnecting pin 49 is removed, the link 52 will be left free to pivot on the lever 24 It can thereafter be very easily swung into place for its attachment with the upper end. of the rod 35;

With the parts connected together and upon the operating lever being raised by the spring re: turn device 26, the piston 31 will be lowered the chamber 14 and valve plate 34 will be raised to permit a charge of liquid to be extended into the chamber 14. As the lever is depressed to raise the rod, the charge of liquid will be forced upwardly through the pipe [6 and out of the st t 1 Referring now to Figs. 7 and 8, there is shown a modified form of construction, comprising a cover 55 to which there is welded a rod 56* for supporting cylinder 57. This rod 56 extends upwardly through the top of the cover and has an opening extending horizontally as indicated at 53 to receive a pin projection 58 of a fastening screw 59-ihaving a knob 61. This fastening screw 59 serves to fix a top casting B2 to the cover 55. The extended end of the shaft 56; provides a lug on the cover for receiving the fastener projecti n 1- At the opposite side of the cover 55-, there is affi ed W and, ex end upw ly therethroush a pi t mmuni a in with c der 5 and s re ihe iaui i and'i i 9- ardly hr vsh the Q ver 5 f r. delivery to a passage 64 in the casting t2; This passage 64 ext ds upwardly and own rd y indicated a o sps sgt eliqu d.
